Dendritic cells (DCs) in tissues and lymphoid organs comprise distinct functional subsets that differentiate in situ from circulating progenitors. Tissue-specific signals that regulate DC subset differentiation are poorly understood. We report that DC-specific deletion of the Notch2 receptor caused a reduction of DC populations in the spleen. Within the splenic CD11b(+) DC subset, Notch signaling blockade ablated a distinct population marked by high expression of the adhesion molecule Esam. The Notch-dependent Esam(hi) DC subset required lymphotoxin beta receptor signaling, proliferated in situ, and facilitated CD4(+) T cell priming. The Notch-independent Esam(lo) DCs expressed monocyte-related genes and showed superior cytokine responses. In addition, Notch2 deletion led to the loss of CD11b(+)CD103(+) DCs in the intestinal lamina propria and to a corresponding decrease of IL-17-producing CD4(+) T cells in the intestine. Thus, Notch2 is a common differentiation signal for T cell-priming CD11b(+) DC subsets in the spleen and intestine.
This research output has an Altmetric Attention Score of 11. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 October 2024.
All research outputs
#4,507,194
of 33,977,172 outputs
Outputs from Immunity
#2,784
of 5,656 outputs
Outputs of similar age
#23,196
of 189,201 outputs
Outputs of similar age from Immunity
#18
of 48 outputs
Altmetric has tracked 33,977,172 research outputs across all sources so far. Compared to these this one has done well and is in the 86th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 5,656 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 33.1. This one has gotten more attention than average, scoring higher than 50% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 189,201 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 87% of its contemporaries.
We're also able to compare this research output to 48 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 62% of its contemporaries.
